This European Standard specifies the technical requirements to minimise the hazards listed in clause 4 which can arise during the commissioning, operation and maintenance of lavatory service equipment when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some requirements recognised as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and handling agencies. This standard applies to: - self-propelled lavatory vehicles; - towable lavatory vehicles; - moveable parts of ramp integrated systems, designed for servicing aircraft and intended to be used under the conditions given in clause 1 of EN 1915-1:2001 (examples see annex A). This standard does not establish requirements for hazards caused by noise and vibration. This Part of EN 12312 is not applicable to lavatory service equipment which is manufactured before the date of publication of this standard by CEN. This part of EN 12312 is intended to be used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.
